I'm glad to see the costume section up and running again. Though there's a couple bugs I'm noticing...
Firstly, "variation" isn't showing up. At least I don't see it anywhere. Also, the series isn't being displayed. The subject title "Series" is appearing, but not the series itself. That field is blank.
And though it may be too late to suggest it now, I might suggest switching around the description section and the picture thumbnail gallery section on the costume pages. Maybe it's just me, but I think it would look better (and make more sense) to have the description area first, and then the thumbnail gallery below it, instead of having the gallery above the description.
As it is now you have to scroll through a wall of pictures just to get to the description.
